Essential oil obtained by hydrodistillation from the leaves of Litsea cubeba Per. and the fruits of L. glutinosa C.B. Robinson (Lauraceae) were examined by GC/MS to determine their chemical compositions. The analysis of L. cubeba was shown that there were at least twenty-semen components. The major constituents were sabinene (42.69 percent), 1, 8 cineole (18.32 percent) and Beta-pinene (6.15 percent). Thirty-six compounds were identified from the oil of L. glutinosa, of which E-Beta-ocimene (45.13 percent), cis-verbenyl acetate (4.40 percent) and 9-epi-E-caryophyllene (4.30 percent) were the major constituents. The oil of L. cubeba was found to be effective against Staphylococus aureus, Bacillus subtilis and Escherichia coli under laboratory screening. The oil of L. glutinosa exhibited a strong antimicrobial activity against Pseudomonas aeruginosa.
